Will a 200w Solar Panel Run a Fridge?

With the current trend in renewable energy, many homeowners are now turning to solar power to meet their household energy needs. One of the most common questions is whether a 200 watt solar panel has enough power to run a standard household refrigerator. While the answer to this question depends on a number of factors, it is possible to run a fridge using a 200 watt solar panel. In this article, we will examine the power source, voltage needs, and system installation to help you make an informed decision about running a refrigerator with a 200 watt solar panel.

Explaining the Power Source

Before we can answer the question of whether a 200 watt solar panel can run a fridge, we first need to understand how solar panels collect and convert the sun’s energy into electricity. The sun emits a wide range of electromagnetic radiation, including visible light, infrared radiation and ultraviolet light. Solar panels are designed to capture this energy and convert it into direct current (DC) electricity. The amount of electricity that can be generated depends on the size of the solar panel and the availability of sunlight.

Measuring Voltage

Most refrigerators operate on alternating current (AC) power, which needs to be converted from DC electricity by an inverter. The power required to run a refrigerator will depend on the size of the fridge and the amount of energy it needs to run each day. To calculate the amount of power needed, you will need to determine the size of your fridge’s battery and then calculate the daily power requirements. You also need to consider voltage drops, which occur when electricity travels through wiring, as this will reduce the amount of power available.

Calculating Run Time

Once you have calculated the power requirements for your fridge, you can compare this to the power output of your solar panel. Most 200 watt panels have a power output of 1.67 amps, meaning that it can provide up to 200 watts of DC power. You will then need to calculate the amperage by dividing the watts by the battery voltage. This will give you an idea of how long the fridge could theoretically run on a fully charged battery.

Installing System

Finally, you will need to consider the installation of your solar panel and battery system. The size and type of wiring you need will depend on the total power output of your system. It is also important to consider the placement of the solar panel and the battery, as direct sunlight and good air flow are essential for maximum energy efficiency. You will also need to factor in the time it will take to install the system, which can range from one to two days depending on the complexity of the setup.


In conclusion, it is possible to run a refrigerator using a 200 watt solar panel, although a number of factors must be taken into account. You will need to consider the power output of the panel, the size of the battery, and the right wiring and installation for your system. Ultimately, with a 200 watt panel and 120Ah battery, you could theoretically power your fridge and lights for over 16 days without needing to charge the battery. Therefore, if you are considering switching to solar energy, a 200 watt panel can provide a reliable source of power for your refrigerator.
